AEROS MH-1: Scientific 3U nanosatellite platform for Ocean monitoring, a precursor of a future blue ocean constellation
The AEROS MH-1 nanosatellite, portuguese flagship program of the MIT Portugal, mission of the year at 2024 Small Satellite Conference held by the AIAA (American Institute of Aeronautics and Astronautics), is collecting a comprehensive set of data of the Atlantic Ocean across spatially distributed areas, spectral wavelengths and time. Now, we can better understand the ocean environment and critical variables in the Portuguese economic exclusive zone. While the AEROS MH-1 is just one satellite, it is a demonstration mission serving as a precursor to a future constellation focused on applying state-of-the-art techniques to measure and monitor the ocean. This project was funded by the MIT Portugal Partnership and designed by 12 different companies, institutes and universities. The work was developed with multinational “Atlantic Interactions” and research efforts.
AEROS MH-1 is a 3U CubeSat hosting three payloads that support the mission’s science and communication objectives. AEROS MH-1’ primary payload is a low-power, compact (70.8 x 70.8 x 105 mm3) hyperspectral imager (HSI). It uses a static spectral filter integrated on top of a CMOS detector to achieve 140 VIS/NIR measurement bands from 470 - 900 nm. A RGB imager provides contextual imagery of overlapping ground scenes for the HSI and serve as a viewfinder for HSI tasking. AEROS MH1 also hosts a software defined radio (SDR) that implements receivers for ARGOS and LoRaWan devices. The SDR supports AEROS MH-1’ objective of improving the connectivity between the biologging tagged marine life and the autonomous vehicles with the biological scientists.
Launched in 4th March 2024, AEROS MH-1 has already provided the first images from space. This capability represents another paramount step in observing the Atlantic Ocean, which will allow a detailed analysis of the marine ecosystem and climate patterns. One more stepping stone for the future constellation.

The RTEMS Qualification Extensions objectives were to identify the users’ needs for communication protocols interfaces and services, to analyse the recent RTEMS versions for management of communications interfaces and monitoring of kernel events. It was implemented in RTEMS by EDISOFT the support drivers for Spacewire and MIL-STD-1553 interfaces for a typical LEON3 processor (GR712RC) and implemented the support for kernel and application monitoring services. Both implementations were provided with the correspondent qualification package for the RTEMS version, including the testsuite covering 100% statement and decision coverage, as requested by the Galileo Software Standards for the Development Assurance Level B. The implementation is provided pre-qualified for the GR712RC board using a single processor implementation of RTEMS.
1-Description
The QuoteDonwloader is freeware software to download stock information from Yahoo Finance to a local MySQL database. It reads from a configuration file the indices and downloads automatically the indices components and places the historical information in the database.
The QuoteDownloader is platform independent software developed in Java and tested in Windows and Linux. The QuoteDownloader works as a background process in three different operation ways. The “daily” download is executed daily at 09:00, local time, and downloads all the indices components stock information of the last twenty four (24) hours. The “weekly” download is executed every Saturday at 09:00, local time, and downloads all the indices components stock information of the last seven (7) days. The “full” download is executed in the first time the QuoteDownloader is run in the computer/database and every first Sunday of the month and downloads all the indices components stock information since 1900.
2-Installation
2.1-MySQL Installation
The QuoteDownloader requires the MySQL database to record the indices components stock information. The user is required to install MySQL in a computer with Ethernet connection to the computer where QuoteDownloader is executing. The database and QuoteDownloader execution computer can be the same machine. The MySQL version used in testing was 5.5.15. It should be compatible with newer versions.
MySQL reference manual can be found in http://dev.mysql.com/doc/. The MySQL version 5.5 installation procedures can be found in http://dev.mysql.com/doc/refman/5.5/en/installing.html.
No special installation procedures must be followed with the exception of a user with full permission to the database where the stock information will be placed. In our example here, the user is “mysql”, with the password “mysqlpassword” and the database where the data is stored in MySQL is named “yahoofinance” (the QuoteDownloader software will create the database in MySQL).
2.2-Java Installation
The QuoteDownloader requires the Java Run Environment to be installed in the computer in order to run. The JRE used in the development and testing of the Quotedownloader is jre6. It should be compatible with newer versions.
To download and install JRE please follow the link http://www.java.com/en/download/index.jsp.
2.3-QuoteDownloader Installation
The QuoteDownloader is formed by three different files.
The QuoteDownloader jar file (download here) is where all the binary and library files are placed and is the software that will run to download the stock information to the database. It is not required any update to this file to install and run the software. Download (download here) and place the jar file in a directory of your computer.
The configuration.dtd (download here) is the configuration file scheme to confirm that the configuration.xml is correctly formed. This file does not require to be updated. Download (download here) and place the file in the same directory as the QuoteDownloader jar file.
The configuration.xml (download here) is the configuration file of the QuoteDownloader program. For a MySQL server installed in the same computer with “mysql” user, with “mysqlpassword” password and yahoofinance database, the configuration file does not require to be updated. Download (download here) and place the file in the same directory as the QuoteDownloader jar file.
3-QuoteDownloader Configuration
The QuoteDownloader configuration.xml is made of four configuration blocks. The HTTPConnection configures the QuoteDownloader connection to the Yahoo Finance site. The Quote configures some indentation of quote information from the Yahoo Finance. The DatabaseConfiguration configures the QuoteDownloader connection with the MySQL database. The QuoteIndices configures the Quote downloader indices and components to be downloaded from Yahoo Finance and placed in MySQL database.
<ConfigurationItems>
<HTTPConnection> </HTTPConnection>
<Quote> </Quote>
<DatabaseConfiguration> </DatabaseConfiguration>
<QuotesIndices> </QuotesIndices>
</ConfigurationItems>
The HTTPConnection and Quote will not be required to be updated.
The DatabaseConfiguration defines the MySQL user (User). If the user defined in step 2.1-MySQL Installation is “mysql”, it will require no update. The Password field defines the password for the user. The IP address for the server is defined in DatabaseName. The Port is the mysql port to be used.
<DatabaseConfiguration>
<User>mysql</User>
<Password>mysqlpassword</Password>
<ServerName>localhost</ServerName>
<DatabaseName>yahoofinance</DatabaseName>
<Port>3306</Port>
</DatabaseConfiguration>
The QuoteIndices provides QuoteDownloader with the information of Indices and Components to be downloaded from Yahoo Finance. Quote Indices are organized by world regions with the zone specified, in the case below, the “US” region. Each world region having one or several indice groups, in the case below the DowJones, and one Indice. The Indice is specified by the Indice name (^DJA – Dow Jones Composite Average) and none or several Components, in the case below the AA – Alcoa Inc. Common Stock. The Component is optional. The QuoteDownloader will discover automatically every Component of the Indice.
<QuotesIndices>

European Space Agency’s effort for providing a radiation tolerant microprocessor to be the heart of future European spacecraft computers has evolved and been demonstrated on the LEON microprocessor. The LEON architecture is based on the SPARC v8 architecture and is a continuation of the ERC32, which was based on the SPARC v7. The intention was to build an architecture that would provide similar performances to the US microprocessors, with an “open source” non-fault-tolerant version for the general European market and develop the LEON architecture for a fault-tolerant and a flight model version. The work activity would consist on the consolidation of the development environment for the LEON, to identify the weaknesses and to implement or propose future implementations to the referred development environment.
